Greensboro vs Aurora

Informations

Greensboro ( (listen); formerly Greensborough) is a city in and the county seat of Guilford County, North Carolina, United States. It is the third-most populous city in North Carolina, the 68th-most populous city in the United States, and the largest city in the Piedmont Triad metropolitan region. At the 2010 United States Census the city population was 269,666. In 2019, the estimated population was 296,710. Three major interstate highways (Interstate 40, Interstate 85, and Interstate 73) in the Piedmont region of central North Carolina were built to intersect at this city. In 1808, "Greensborough" (the spelling before 1895) was planned around a central courthouse square to succeed Guilford Court House as the county seat. The county courts were thus placed closer to the geographical center of the county, a location more easily reached at the time by the majority of the county's citizens, who depended on horse and foot for travel. In 2003, the previous Greensboro – Winston-Salem – High Point metropolitan statistical area (MSA) was re-defined by the U.S. Office of Management and Budget. This region was separated into the Greensboro–High Point MSA and the Winston-Salem MSA. The 2010 population for the Greensboro–High Point MSA was 723,801.

The combined statistical area (CSA) of Greensboro–Winston-Salem–High Point, popularly referred to as the Piedmont Triad, had a population of 1,599,477. Among Greensboro's many notable attractions, some of the most popular include the Wet 'n Wild Emerald Pointe water park, the Greensboro Science Center, the International Civil Rights Museum, the Weatherspoon Art Museum, the Greensboro Symphony, the Greensboro Ballet, Triad Stage, the Wyndham Golf Championship, the headquarters of the Atlantic Coast Conference, the Greensboro Coliseum Complex which hosts various sporting events, concerts, and other events. Sports Leagues in Greensboro include the Greensboro Grasshoppers of the South Atlantic Baseball League, the Carolina Dynamo of the Premier Development Soccer League, the Greensboro Swarm of the NBA G League, and the Greensboro Roller Derby. Annual events in Greensboro include the North Carolina Folk Festival, First Fridays in Downtown Greensboro, Fun Fourth of July Festival, North Carolina Comedy Festival and Winter Wonderlights. From 2015-2017 Greensboro, North Carolina was host to the National Folk Festival. The Greensboro Convention and Visitors Bureau (GACVB) makes an annual visitors guide showing the city as a destination to visit.

An aurora (plural: auroras or aurorae), sometimes referred to as polar lights (aurora polaris), northern lights (aurora borealis), or southern lights (aurora australis), is a natural light display in the Earth's sky, predominantly seen in high-latitude regions (around the Arctic and Antarctic). Auroras are the result of disturbances in the magnetosphere caused by solar wind. These disturbances are sometimes strong enough to alter the trajectories of charged particles in both solar wind and magnetospheric plasma. These particles, mainly electrons and protons, precipitate into the upper atmosphere (thermosphere/exosphere).

The resulting ionization and excitation of atmospheric constituents emit light of varying color and complexity. The form of the aurora, occurring within bands around both polar regions, is also dependent on the amount of acceleration imparted to the precipitating particles. Precipitating protons generally produce optical emissions as incident hydrogen atoms after gaining electrons from the atmosphere. Proton auroras are usually observed at lower latitudes.
